Scientists Confirm Cellular Basis for Memory by Implanting and Erasing Fear in Rats

June 2, 2014

0 Comments

In a newly published study, scientists at the University of California show the ability to selectively remove a memory and predictably reactivate it by stimulating nerves in the brain at frequencies that are known to weaken and strengthen the connections between nerve cells. Researchers at the University of California, San Diego School of Medicine have […]

Using light-field microscopy, researchers demonstrate the new technique that allowed them to simultaneously image the activity of every neuron in the entire brain of a zebrafish larva. Researchers at MIT and the University of Vienna have created an imaging system that reveals neural activity throughout the brains of living animals. Video: Melanie Gonick/MIT Researchers at […]

Infusion of Young Blood Reverses Age-Related Impairments in Mice

May 6, 2014

3 Comments

A newly published study from Stanford University found that an infusion of young blood can counteract and reverse pre-existing effects of brain aging at the molecular, structural, functional and cognitive level in mice. Something — or some things — in the blood of young mice has the ability to restore mental capabilities in old mice, […]

Researchers Use Stem Cells from Teeth to Grow Brain-Like Cells

May 1, 2014

2 Comments

New research from the University of Adelaide shows that stem cells from teeth can develop and form complex networks of brain-like cells. University of Adelaide researchers have discovered that stem cells taken from teeth can grow to resemble brain cells, suggesting they could one day be used in the brain as a therapy for stroke. […]

Neurobiologists Block the Effects of Stress

April 14, 2014

1 Comment

By deleting the REDD1 gene in mice, researchers from Yale University were able to block the synaptic and behavioral deficits caused by stress. Ketamine, an anesthetic sometimes abused as a street drug, increases the synaptic connections between brain cells and in low doses acts as a powerful antidepressant, Yale researchers have found. However, stress has […]

Scientists Reveal 3D Structure of the Molecular Transporter TSPO

March 24, 2014

1 Comment

Scientists have revealed the 3D structure of the molecular transporter TSPO for the first time, opening the door to novel paths for the diagnosis and treatment of brain diseases. The word “cholesterol” is directly linked in most people’s minds with high-fat foods, worrying blood test results, and cardiovascular diseases. However, despite its bad reputation, cholesterol […]

Neurobiologists Reveal Age-Related Changes that Answer Key Questions about Alzheimer’s Disease

March 19, 2014

0 Comments

In a newly published study, neurobiologists reveal age-related changes that help to answer key questions about Alzheimer’s disease. With advancing age, highly-evolved brain circuits become susceptible to molecular changes that can lead to neurofibrillary tangles — a hallmark of Alzheimer’s Disease, Yale researchers report the week of March 17 in the Proceedings of the National […]

Researchers Use Brain Signals to Move Paralyzed Limbs

February 20, 2014

0 Comments

A newly published study details a cortical-spinal prosthesis that directs “targeted movement” in paralyzed limbs. Ithaca, New York – To help people suffering paralysis from injury, stroke or disease, scientists have invented brain-machine interfaces that record electrical signals of neurons in the brain and translate them to movement. Usually, that means the neural signals direct […]

Gene Linking Brain Structure to Intelligence Identified

February 12, 2014

1 Comment

An international team of scientists has identified a gene linking brain structure to intelligence, finding that teenagers carrying a particular gene variant had a thinner cortex in the left cerebral hemisphere and performed less well on tests for intellectual ability. For the first time, scientists at King’s College London have identified a gene linking the […]

How the Anatomical Structure of the Brain Impacts Its Functioning

January 16, 2014

1 Comment

By simultaneously analyzing 1.6 billion connections within the brain, researchers have discovered how the architecture of the brain shapes its functioning. The structure of the human brain is complex, reminiscent of a circuit diagram with countless connections. But what role does this architecture play in the functioning of the brain? To answer this question, researchers […]

Study Shows Human Brain Development is Divided into Three Major Phases

December 27, 2013

1 Comment

In a newly published study, researchers analyzed gene expression in human and macaque monkey neocortex, finding that human neocortical development is divided into three major phases. The human brain develops with an exquisitely timed choreography marked by distinct patterns of gene activity at different stages from the womb to adulthood, Yale researchers report in the […]

Study Shows Oxytocin Improves Brain Function in Children with Autism

December 3, 2013

3 Comments

A new study from Yale University is the first study to evaluate the impact of oxytocin on brain function in children with autism spectrum disorders, finding that a single spray of oxytocin improves brain function in children with autism. A single dose of the hormone oxytocin, delivered via nasal spray, has been shown to enhance […]
